SACK-BAUER.

Patented Apr. 24, 1917. Application filed August 20, 1915. Serial No.46,510.

Specification of Letters Patent.

To all whom it may concern:

Be it known that 1, WILLIAM A. Vinnsrnn, a citizen of the United States,and a resident of Galesburg, in the county of Knox and State ofIllinois, have invented a new and useful Sack-Baler, of which thefollowing is a specification.

My improvements relate more particularly to devices for baling cement,salt and other sacks with wire and for securing the ends of thebale-wire together after the bale is 001m pleted. However, it will beevident. as the nature of the invention is further disclosed and betterunderstood, that the improvements are of such nature that they may beemployed vith equal success for baling and tying bundles of angle andother irons, ax, fork and other handles, and for other pur poses toonumerous to specifically enumerate.

The present invention is purposed and designed as an improvement on themachine disclosed in Letters Patent granted to me April 13, 1915, No.1,135,931, and the improvements are directed mainly toward the provisionof pivoted levers which constitute a part of the frame, said leversadapted for purposes presently more fully described; toward theprovision of packerarms or forks; toward the means for temporarilyholding the wire in order that it may sustain the sacks before they arecompacted; toward the provision of a frame especially adapted to coactwith the means above recited and with the means next recited; toward theprovision of specially constructed wire-tying devices,

' whereby they will not become disassembled when the above noted pivotedlevers are reversed from their normal positions; toward other novelfeatures included in the tying devices: and toward minor novel featureshereinafter described. 1

The objects of the'invention are, therefore, to generally improve theconstruction and to increase the capacity,utility and efiiciency ofdevices of this character.

By way of example a baling press embodying the features of the inventionis illustrated in the accompanying drawings, in which:

, Figure 1 is a perspective, a quantity of sacks being sustained, by thebaling wires, in position for compression and for tying.

Considering the drawings in detail and referring to the elements and.where necessary, to the parts thereof. each by a distinguishingcharacter, uniformly employed, 22 designate supporting archesofchanneliron. 3-3 designate cross-bars, the bent ends of each of whichare secured to the legs of the arches 2 as presently more fullydescribed. 4E4c designate channel-iron struts. 55 (Figs. 10 and 11)designate frame-barlocking inserts, comprising each a longitudinallyarranged arm or branch 6 and a transversely arranged arm or branch 7said arms lying in diiferent horizontal planes and each insert providedwith an aperture 5 passing through both branches. The arm 6 rests in thechannel of the strut and the arm the lever shown top-plan of one of thepacker- 7 in that of the arch, and a bolt or rivet 8 is passed throughthe strut, the insert, the leg of the arch, and the cross-bar, to holdthem rigidly together, as is essential in this class of devices. In Fig.8 I have shown a modified form of insert, 5, to be used when the channelof the strut is faced outward. The arm 6 would then lie in the channelof the arch, and the recess 7 would receive and rigidly hold the strutfrom movement relatively thereto. In Fig. I have shown another modifiedform of insert 5, this one purposed for use when the strut runs atanother angle than a right one relatively to the arch. 9, 9 indicate thelongitudinal, and 10,10 thetransverse bars of a sack-receiving anddelivering table, the bars 9, 9 being securedto the arches 2 and thebars 10, 10 to thebars9,9.

1 1,,11 designate hinge-butts secured in coacting pairs on the forwardand rear corners respectively of the arches andprovided each with aforked end having eyes 12. .13, .13 indicate frame-levers having each aneye 14, a. foot and a tongue 16. 17, 1'1 designate bolts passed throughthe eyes in the pairs of hinge-butts and levers, and they serve aspivots for the latter. 18 designates a pivoted frame-bar secured at 19to the swinging ends of the levers 13, and 20 designates a similar barsecured to the levers 13, I

21, 21 designate packer-forks fixed each by a bolt 23 passed through theeye 22 thereof, to; the frame-bar 20, the tongue 24: eX- tending over anedge ,and the inclinedpor: tion 25 resting on the plane lower face ofsaid bar whereby to incline each fork normally downward.

, 26 indicates the stationary disk member of the wire-twisting or tyingmeans and com prises a base having a radially arranged" mouth 28extending 1n rear of its ax s, a

peripheral groove 29, and a projection 30 having an aperture 31 for thereception of suitable means for securing it to the bar. 18. Of thesedisk members, and of they parts cooperating therewith and now to bedescribed there-may be any suitable number. 32 designates atwisting-head or hub having a crank-handle 33, its bottom provided witha radially cut slot 34 terminating in a flared mouth 35 which cuts alsothe rim 36 Said bottom. and rim form a socket rotatable on the disk 26.37 indicates aset screw threaded through an aperture in said flange, itspoint extending into the groove 29.

To ,assemblethe wiretying members the mouth 28 is positioned over saidscrew-point and .the disk then dropped into place in the socket. -Uponit being rotated the screwpointwill enter thegroove 29 and prevent theelement 32 from dropping oftthe disk 26., when-theframes. are swung tothe reversed positions shownin Fig. 9. 38 indicatesa wire-holding pinfixed in the member 32.

For initial securement of one end of the wire I have provided the meansshown best in Fig. 12, one set of these means cooperating with eachtying mechanism. 39 designates a, crank-screw onto which a nut 40 istightly threaded. The stem of said screw is then passed loosely throughan aperture 41 in the vertical arm of the bar 20 and its end portionengaged with the free end portion of a. spring clamp-plate 42, the otherend of said plate being secured by a bolt 43 and nut 41 to said arm andspaced therefrom by a washer 45.

To operate the device the pivoted frames are swungto the horizontal openpositions shown in Fig. 9, in which positions they will be maintainedbecause of the shoulders 46 (Fig.16) of the frame-levers coming upagainst the ends 47 (Fig. 15) of thehingebutts. One end ofeachbalingwire 4:8 is then placedbetweenthe bar.20 and spring 42 (see Fig.12) andthe screw 39 .given a part rotation to draw on said spring andthereby clamp the wire. The other end of eachwire is then passed throughthe mouths of the tying elements and wrapped around the pin 38. Thesacks 49 are then laid one upon another. on said wires, and when asufficient number has. been thus piled the pivoted frame 50 is swung totheposition shown in Fig.1, the frame 51 meanwhile beingswung on itspivot but its throw not completed until after the frame 50 has reachedits final position of rest. (These movements may. of course be slightlydeviated from.) As the packer forks 21 were swung they pressed overandheld down the edges of ,the sacks, compacting them into properbale-form, the wires meanwhile closing around and forming loops on thebales and drawing the sacks into positions for tying. The operatorthentwists around the pin 38 theprojecting end of that portion of thewireheld by the clamp l2, thus bringing it. through the mouths of thecoacting tying elements and into the slot 34;, and then rotates thehandle 33 clockwise, the adjacent wall of themouth 35 striking the wireand freeing it from said clamp. Continued rotations of the element 3233will, by twisting the wire ends about each other as shown in Fig. 7,shorten the .loop and cause it to tightly bind and compress the bale ofsacks.

When the tying operation has been completed the wires are released andthe bales will fall onto the. inclined delivery table 910 from whencethey will roll onto the floor atthe front side ofthe machine, where theymay be readily handled.

The feet 15 rest, when in normal position s, each in the channel of oneof the sup.- porting arches 2, whereby the bars 18 and 20 and thereby.the tying and packing means are supported. I

I have shown and described that embodiment of my invention which is atpresent preferred by me, since it has in practice been found to givegratifying results, but have not deemed it necessary to encumber thespecification and drawings with descriptions and illustrations ofmodifications which are neither essential to nor form any part of theinvention, considered in its broadest aspect. In fact, it will be quiteevidentthat numerous structural changes may be made, and that some ofthe parts may be used without the others and without departing from thespirit and scope of the invention. Therefore, without limiting myself toparticularities except in those places in which they are specificallyrecited, I claim as new the following to-wit:
